Functional FIPS: Learning PHP for Drupal Theming
- 2. About this talk ● There are a lot of theme snippets available in the Theme Guide. There is not, however, a lot of information about PHP which is the language that makes up these snippets. If you're tired of copying, pasting and praying and are ready to understand some of the magic behind those snippets, this session is for you! ● In this session you will learn how to manipulate and master: ● The very, very basics of PHP and the popular theming engine PHPtemplate ● Variables and tpl.php template files ● Arrays and objects and other crowbarworthy data containers. ● The really scary looking stuff that's in the mysterious file template.php ● Examples will be pulled from the Drupal.org Theme Guide as well as the wildly successful book on theming, Front End Drupal (coauthored by Emma Jane and Konstantin Kaefer).

' by ' . theme('username', $node); } else { print 'By ' . theme('username', $node) . ' <br /> ' . format_date($node>created, 'custom', "F jS, Y") ; } ?> </span> <?php } ?>
- 38. Summarizing PHP for Designers ● PHP is a linear “programming” language, just like a dance. ● PHP stores information in variables. ● Sometimes variables hold lots of information in special variables called “arrays.” ● Drupal has lots of magic variables that are loaded with content.
